10 Freaky Ingredients Found in McDonald’s Food that Will Make You SICK!

mcdonalds sick FI

Here’s what I want you to do. Picture a juicy Big Mac with a side of fries. Just think about that juicy beef, that sesame seed bun and melty American cheese.

Are you salivating yet?

Well, brace your taste buds. They’re about to hit a massive brick wall.

Everybody knows McDonald’s has one of the worst reputations of any restaurant among health experts. But most people don’t know why.

Obesity is just one of the reasons. In reality, there are several more reasons– which shouldn’t come as any surprise if you’ve ever taken a look at some of the ingredients McDonald’s products contain.

Let’s have a look at 10 freaky McDonald’s ingredients that should flip your appetite off the stuff for good.

1. Ammonium Sulfate


Ammonium sulfate is an inorganic salt. Its main purpose? Fertilizer. It’s also added to Monsanto’s Roundup to make it more effective.

Here’s another fun fact for you – ammonium sulfate is also in flame retardant!

Effects of eating ammonium sulfate include hormone disruption.

2. Silicone Oil


Did you lose your contact lens in your McNuggets again? Don’t worry, just keep eating; it’s totally safe to eat.

At least that’s what McLogic seems to imply, since the very same material that is used to make contact lenses is used in McNuggets.

Known as dimethylpolysiloxane or silicone oil, the chemical is also used in caulking, lubricants and silly putty.

Silicone oil is non-biodegradable and its use has been decreased in breast implants due to safety concerns. Leakage of the chemical into bodies of water has also been found to harm marine life.

But 37 million bite sized nuggets laced with the chemical? No problem. Duh, McLogic.


Looks delicious, don't you think?

TBH, I don’t know why anyone would want to eat anything with a name long enough to warrant a four-letter acronym.

And yet, TBHQ is found in many commercial foods, from crackers to chips and, of course, fast food.

It’s also used in cosmetic products, lacquers and resins.

Despite referring to TBHQ as “totally safe,” the FDA has set a strict limit on how much of the stuff can be placed in food.

Studies have shown that consuming TBHQ long-term can result in aggravation of ADHD symptoms, stomach cancer and damaged DNA.

And considering that many people (wrongly) assume fast food is the only thing they can afford to eat, it’s fair to say there’s a good chunk of people out there who have been eating McDonalds on a regular basis for a while.

4. Propylene Glycol


Hey, you like antifreeze? I do – but to be honest, I prefer to put it in my car instead of my food.

Propylene glycol is the chemical that makes antifreeze absorb water.

It’s also used in the treatment of burns, where it can have severe negative effects if kept around your body for too long.

Those with existing eye conditions, skin conditions and allergies (so basically, most of the population) have increased sensitivity.

It can also cause central nervous system depression.

5. Carminic Acid


Carminic acid is produced by insects to deter predators.

Clearly, it’s not much of a deterrent to humans though, who literally crush the bugs and place them in food products as a means of food coloring.

About 70,000 insects are killed, crushed and soaked in alcohol to produce a pound of dye. But of course the fast food industry doesn’t bat an eyelash; animal cruelty is pretty much a business model there.

And if the whole “thousands of crushed insects in my meal” thing doesn’t freak you out, don’t worry – carminic acid has also been tied to asthma, diarrhea and a host of other nasty bugs.

6. Cellulose

Would you like some wood with tha– actually, you don't have a choice.

Also known as processed wood pulp (as if ordinary wood pulp in your food wasn’t bad enough), cellulose is found in pretty much every fast food item. It’s in cheese, salad dressing, muffins, strawberry syrup… you name it.

Cellulose is one of the main ingredients in low-carb foods. It’s a bit of a “cheat ingredient” because it makes up a portion of the substance of such foods. So yeah, technically you’re not eating a whole lot of carbs in that burger but you are eating lots of indigestible wood.

Leave it for the termites, man.

7. Industrial Sand


More formally known as silica, industrial sand is used to make glass, optical fibers and cement. Fast food restaurants like McDonald’s also toss the stuff in their meat to prevent clumping.

It’s dangerous to breathe; in industrial settings, hazmat suits and masks are used to protect workers. But in your burger? No problem! McLogic, man.

8. Cysteine-L


Cysteine-L is an amino acid synthesized from human hair and duck feathers. It’s used to flavor meat and soften breads and pastries.

WebMD reports that it can cause vomiting, diarrhea, constipation, rashes, fever, headache, drowsiness, low blood pressure and liver problems.

9. Prescription Medications


There’s an alarming amount of prescription medication in chicken feed including antidepressants and even some banned drugs.

A study from Johns Hopkins University found that, unsurprisingly, these banned medications wind up in chicken products from fast food restaurants.

10. Dimethylpolysiloxane


This is a chemical commonly used in silly putty and breast implants. It also contains formaldehyde, a chemical that is a known carcinogen.

So if a Big Mac makes a terrible snack, what should you eat? Check out the video below to find a healthy, great-tasting natural food.

A) sand, cellulose, and carminic acid really aren’t that bad, are technically natural and capable of being handled by your body.

B) You were clearly reaching for more ingredients. You didn’t even get to 10. ..

    Cmj - June 5, 2016

    Aren’t that bad? Just a little bad is bad on top of all the other poison in our food now thanks to the whores in WDC allowing Monsanto, DuPont and other chemical companies poison our food and our soil. People in this country are very stupid for not paying attention and raising hell, especially if you have kids. Factory farms are the worst thing to happen to our food chain.

      John Bespmir - June 21, 2016

      We cannot stand afraid of every single food additive. Many of the ones we use are bad, like the artificial sweeteners and synthetic salt preservatives, but we clearly see that they serve a purpose. Look at the almost immeasurable variety of food we’ve been able to make. Imagine if we find healthy, and usable alternatives that allow us to continue to create all of these varieties? Sand in small amounts is extremely useful, non clumping is huge, and the amount needed is inconsequential. You probably would consume more if you fell on the beach. Mammals evolved around dirt, we are well capable of handling it. It won’t hurt, and it serves a very useful, functional purpose. That is just one example of a non harmful additive that only serves to improve our capabilities of food production.

      I say this as a whole food vegan. I want advancements, but I want them understood and non harmful. That said, why not explore what’s out there, see how it effects us and continue to explore our environment? We can only ever truly understand what’s out there by interacting with it. The way we’re doing this now non is unethical often ignoring evidence of harm, and done with money in mind, but I don’t think that should remove our interest and desire to find new foods in an ethical fashion.

    I read 10…..

      Two and 10 are the same thing

An how exactly do you know what ingredients McDonalds’s is using? McDonald’s should sue you if you got any of them wrong (will contact McDonald’s regarding this). Also, since you’re so concerned about health issues, you might as well hide in a cave because I have news for you, sunlight can cause skin cancer.

    Kathy - August 11, 2016

    McDonald’s tried suing the Chef who had a laboratory analysis done on some of their foods. I believe that it may have been Jamie Oliver, but can’t swear to it. The laboratory results were not in McDonald’s favor. I believe that they quietly dropped the suit.

fxxx that, been eating mc donalds since the past 40 years. i put a lot of avocado in my big mac.
ever wonder why David has man tits? being healthy and all he should not eh? maybe David should work out more I guess. my body at 85 is much more solid then his. LOL on mc donalds probably 4 x a week, love the place

Jeff McCrory - June 5, 2016

Did you really need to read this to realize fast food is horrible in so many ways? Sure, you can go 40 years eating it, just means you have very, very, very good genes and you have avoided, thus far, a mass coronary. You know there are so many preservatives in fast food, it litterally will not decmpose…..correct…..maggots won’t even eat it…..look it up.

Lisa Johnson - June 5, 2016

I talked with someone who worked at ADM. He said that they make processed soy to look and taste like mushrooms and green and red peppers and sell them to Pizza Hut. Allergic to soy? don’t eat at Pizza Hut

Álvaro Gomes Aguiar - June 6, 2016

McDonald’s, Subway, fastfoods, alguns integrais, outros = Azodicarbonamida (liberado no Brasil) + Nitrosaminas = manifestação de câncer em quem tem predisposição, além de distúrbios gastrointestinais. Ou seja, você come pedaços de plásticos, solas de sapato e conservantes pesados achando que é o “senhor natura”. Por que vocês acham que os pães deles são sempre macios, duradouros e elásticos, além de outros ingredientes apelidados de frescos ou naturais? Isto tem um nome muito conhecido. Junk + Food. Junkfood. Mas que cheiram bem e são bonitinhos, isto são. ;)

1. Ammonium Sulfate
Recognized as safe by the FDA.

2. Silicone oil (or polydimethylsiloxane)
Also recognized as safe. Since this is the same as #10, it does not contain formaldehyde. The two do not even have remotely similar chemical structures. It can seep into groundwater and isn’t biodegradable, but treatment facilities regularly decompose it. It is used to keep the cooking oil from splattering and popping.

The levels that cause negative health effects are so much higher than what is allowed by the FDA in your food that you have no reason to worry. It’s a fat preservative.

4. Propylene Glycol
It is also used as a preservative. In order for you to reach toxic concentrations, you would probably have to eat so much McDonald’s that your stomach would explode first.

5. Carminic Acid
I couldn’t find much on this one, but it is possible for chemists to synthesize it in the lab. Seems unlikely to me that they’d farm beetles to squish, considering all they want is the trace quantities of dye.

6. Cellulose
This one is intentionally deceptive on behalf of the author, and there is no sugarcoating it. Cellulose is not just in wood. It’s a generic plant fiber. In your food? Certainly. Every time you eat lettuce, celery, bran cereal, or practically any plant, you are consuming cellulose. It’s also known as “indigestible fiber,” which is an essential part of the human diet if you ever intend on going to the bathroom again.

7. Industrial sand
This is dangerous for the same reason a coal mine or a wood shop is dangerous: the particles are fine enough to get stuck in your lungs. There is nothing inherently dangerous about silica, and you’ll find it added to seasonings like paprika and cumin to prevent clumping, too. If you breathe it in, yeah, you’re going to have problems. But mixed in with your food in trace quantities? Not likely.

8. L-cysteine
This is a naturally occurring chemical that your body produces. It is an amino acid, which means that it is necessary for protein production. It is considered non-essential because your body produces it (unlike essential amino acids), but there are rare cases where individuals suffering from certain metabolic disorders may need an outside source. Sure, if you eat twelve pounds of it, it probably isn’t good for you, but you already eat it whenever you consume any complete protein, including any animal meat, dairy products, or things like quinoa. In the quantities added, it is almost certainly not dangerous.

9. Prescription medications
Farmers regularly give their livestock things like antibiotics. I can’t see them giving them antidepressants unless it also happens to serve another purpose. If it was really such common knowledge that illegal drugs were added to chicken feed that a generic health conspiracy blogger could find out, the FDA would be on them faster than a pig on a mud hole.

10. See #2

Does that mean McDonald’s is healthy? No. But you probably won’t die from it. I don’t eat there because I don’t like the way their food tastes. Why do I care, then? Because bad science and misinformation bothers me.

    Melinda - June 12, 2016

    The FDA approved many things that are later recalled as crazily dangerous. And it doesn’t approved peppermint oil to help with nausea or cinnamon to be a antibacterial. When obviously both are true. Fda approved may be the worst way to figure out if something is safe. It’s all about the money trail.

      Jacob - June 12, 2016

      No rigorous scientific experiment performed has ever proven that cinnamon has any medicinal qualities, and the data on peppermint is very conflicted (and I like peppermint, myself).

      If you ate a Big Mac, fries, and a soda for every meal for ten years straight, your health problems would be consistent with those found in a diet high in sugars and partially hydrogenated fats whilst being low in important vitamins and minerals. In other words, you would die of diabetes, a massive coronary, or vitamin deficiency-related illnesses long before any of those “toxic” ingredients would kill you.

        Melinda - June 12, 2016

        Lol no rigorous studies exist because you can’t patent cinnamon. And actually there’s plenty of studies. There’s a lovely pub med doc on On Guard (essential oil) effectively attenuating the flu virus. But the fda won’t let anyone say it does. It’s all about the money. And anyone who isn’t tied to the fda/pharma money trail can see it. These fda approved poisons are killing people. Asthma allergies autism ADHD obesity diabetes …all fda approved.
